His second attack is Wonder Flare, which costs 1 Fire and 3 Colorless Energy (any energy) to use. It does 80+ damage. The additional damage is decided by the number of Energy cards in your opponent’s hand. Your opponent reveals his or her hand, and the attack deals 40 damage for each Energy card revealed. This is potentially a devastating attack, considering how many Energies players can have in hand at any given time.
The only reason downside to this card is the fact that it’s weak to Water. By as soon as Turn 3, Delphox EX could be causing devastating damage to opponent’s Pokemon. Your opponent will need to find ways to play more Energy from their hand in a turn or have to discard Energies simply not to take more damage from Wonder Flare. I am a huge fan of this particular EX card, and the fact that I’m a huge Delphox fan in general makes this a card I definitely would want for my collection. We’ll see how he becomes used in the upcoming Modified format.
